These standards are constructed of wardly into the tray and are distributed as they 30 any suitable sheet metal, preferably steel, as more accumulate, until the tray is substantially filled. clearly illustrated in Fig. 5, in which it will be To facilitate the handling of sheet material noted that the sheet metal is bent to generally and the spacing of the perforations therein, an rectangular form, providing bottom and top embossed indicator 32 is provided on the surface 35 members I2 and I3 and sides I4 with projecting Yof the base 5. There is also a depression 33 in 35 ears I5. The bottom I2 and top I3 are provided the surface of the base 5 to afford a support for with oppositely disposed openings I6 and I1 to a guide 34 which is preferably split at 35 to receive and guide the punch I 8. To assure proper afford a friction engagement. A projection 36 alignment 0f the DllnCh and t0 pleVenl'f escape 0f at the end of the guide provides a limit for the 40 the lower ond thereof from the Opening in the edge of the sheet material.

Various changes may be made in the details of construction and arrangement of the parts Without departing from the invention or sacricing any of the advantages thereof.

We claim:

1. A perforating devi'ce comprising a base, standards thereon each of sheet metal bent to provide a top and bottom with guide openings therein and projecting ears, punches supported in the guide openings and an operating lever pivotally connected to the punches and fulcrumedv in slots formed in the ears, the slots being disposed With their axes in angular relation to a. horizontal plane parallel to the base.

2. A perforating device comprising a base, standards thereon each of sheet metal bent to provide a top and bottom With guide openings therein and projecting ears, a boss formed from the body of the metal and surrounding each bottom guide opening, punches supported in the guide openings and an operating lever pivotally connected to the punches and fulcrumed in slots formed in the ears, the slots being disposed With their axes in angular relation to a horizontal plane parallel to the base.

3. In a perforating device, a standard adapted to support a punch and consisting of sheet metal bent to provide a top and bottom with guide openings therein, and projecting ears having slots therein disposed with their axes in angular relation to a horizontal plane parallel to the bottom of the standard.

4. A perforating device comprising a base, standards thereon each of sheet metal bent to provide a top and a bottom With guide openings therein, a pair of projecting ears extending up- Wardly from each of said standards, a fulcrum pin journaled in each pair of ears, punches supported in the guide openings, and an operating lever connected to the punches and fulcrumed on said pins.

5. A perforating device comprising a base, standards thereon each of sheet metal bent to provide a top and a bottom With guide openings therein, a pair of ears projecting upwardly from each of said standards and each provided with an elongated slot, a fulcrum pin journaled in each pair of ears and positioned in said slots, punches supported in the guide openings, and an operating lever pivotally connected to the punches and fulcrumed on said pins.
